Abstract (en)
[origin: US2018036743A1] Processes for enriching a desired mineral from an ore comprising the desired mineral and gangue, are provided, wherein the process comprises carrying out a flotation process in the presence of one or more chelating agents, one or more collecting agents, one or more types of multivalent metal ions, and optionally, one or more depressants, in a solution, wherein the one or more chelating agents are capable, alone or as a group of compounds, of sequestering a metal or metal ion in the form of a metal-chelating agent complex that remains at least partially soluble in the solution.
